Our test bench was comprised of only the latest and greatest components to make sure that the Rampage III Extreme could really be used to its full potential. Although our Engineering Sample CPU did not overclock very well on air cooling or water cooling, this was a limitation of the processor and not the motherboard.
|Processor||Intel Core i7 980x ES|
|Memory||Corsair Dominator GTX2 6GB 3x2GB|
|Motherboard||ASUS Rampage III Extreme|
|Hard Drive||Corsair Force 120GB|
|Video Card||NVIDIA GeForce GTX480|
|OS||Windows Server 2008 SP2 (Vista 32-Bit)|
To start things off, we started with 3DMark Vantage, the latest 3D benchmark from Futuremark. Although this may not use the latest DirectX 11 and other features, it is still one of the most popular benchmarks today. With everything at bios defaults we ran the test and ended up with a score of 22,569 3DMarks.
Next up we had the new Mafia II Demo benchmark to represent a current game benchmark. Although the screenshot only says it received a rank of C, the limitation was our graphics card. At stock settings we got 58.7 frames per second.
To test memory bandwidth we used the 2010 version of SiSandra. Although the memory controller has moved to the processor with the current Core i7 processors, memory bandwidth is still important. With the memory at bios defaults the score was still a respectable 20GB/s.
Next up is the Super Pi 1M and 32M benchmarks. SuperPi is a very interesting benchmark because as much as it relies on CPU, memory frequencies and timings, it also relies heavily on the system bios. Slight tweaks to the bios can make the world of difference especially in the SuperPi 32m where it can make up seconds. Super Pi 1M finished in a time of 12.292 seconds and 32M finished in a time of 11minutes and 21.158 seconds.
The final benchmark is wPrime 32m and 1024m. This is a multi-threaded benchmark that is going to load the processor to 100%. The 32m test finished in a time of 4.992 seconds and the 1024m test finished in a time of 151.18 seconds
Overclocking this board was very easy and only took a matter of a few minutes to reach the limit of our processor. The final settings had the base clock at 200MHz with the 22 multiplier for a speed of 4.4GHz at 1.45v. Our maximum base clock achieved was 214MHz. Unfortunately this was the limit of our Engineering Sample processor. We also were able to overclock the memory with ease to 2000MHz 7-7-7-20-1T.
We ran 3DMark Vantage to get the overclocked score. Our new score of 22,716 3DMarks did beat the stock score by nearly 200 points, but the thing to look at is how much the CPU test gained. Our previous score was 69,350 and our new score was nearly 1,000 points above that at 70,163.
We re-ran Mafia II with the overclocked CPU and memory, however it did not improve our score much. Again this was due to a GPU limitation in the game. The final FPS rating was 58.9 FPS.
For memory bandwidth, we re-ran SiSandra 2010 memory bandwidth benchmark and the memory bandwidth was now at 25.78GB/s with the overclocked processor and memory.
SuperPi had the most noticeable difference when overclocking the system. The SuperPi 1M finished in 9.5 seconds beating the previous by 2.792 seconds. The 32M benchmark also saw great improvements as the time dropped down to 9 minutes and 9.856 seconds an improvement of 2 minutes and 11.302 seconds.
Although our wPrime 32m score only improved by 0.032 by overclocking our 1024m time was faster by 4.165 seconds.
